MBSE Grid: A Simplified SysML‐Based Approach for Modeling Complex Systems

Abstract

After an organization makes the decision to adopt model‐based systems engineering (MBSE), it must go a long way before this decision proves right. There are many obstacles in this way, like stories about unsuccessful MBSE applications, insufficient information on how to proceed, and employee resistance to the cultural change to name a few. Neither of them is a true issue, if suitable enablers for MBSE adoption are chosen. Nowadays, MBSE is enabled by Systems Modeling Language (SysML). However, SysML is neither a framework nor a method: it provides no information about the modeling process and thus must be combined with some methodology to become truly applicable. This paper summarizes the experience of various MBSE adoption projects in the form of a new approach for MBSE. The approach is based on the framework organized in a matrix view and is designated to guide system engineers through the modeling process and help them answer the questions, like how to start, how to structure the model, what views to build, which artefacts to deliver, and in what sequence.

Towards Solving MBSE Adoption Challenges: The D3 MBSE Adoption Toolbox

“…Analysis of MBSE methods and enterprise architecture frameworks reveals that the majority are conceptual and thus can hardly be used in combination with modeling languages, such as SysML, in practice. In contrast, the MBSE Grid approach proposed by (Morkevicius et al 2017), (Mazeika et al 2016) is fully compatible with SysML. Based on a transparent system architecture framework, it clearly defines the modeling process, reveals what model artefacts should be produced in each step of system lifecycle, and explains how to manage traceability relationships.…”

“…It is designed to guide system engineers through the modeling process by helping them answer questions, such as how to organize the model, what is the modeling workflow, what model artefacts should be produced in each step of that workflow, how these artefacts are linked together, etc. (Morkevicius et al 2017), (Morkevicius & Jankevicius 2015).…”

Systems of systems: From mission definition to architecture description

“…MagicGrid is a SysML‐based framework for modeling complex systems. The MagicGrid framework consists of viewpoints (black box, white box, and solution) and aspects (the four pillars of SysML: requirements, system structure, system behavior, and parameters) organized in a grid view.…”

“…The MagicGrid framework consists of viewpoints (black box, white box, and solution) and aspects (the four pillars of SysML: requirements, system structure, system behavior, and parameters) organized in a grid view. The cells of the grid represent different views of MBSE, which are described as follows: (a) the requirement elicitation of stakeholders by using the SysML requirement (RE) diagram; (b) a use case description of the refinements of functional stakeholder needs; (c) system context representation using the SysML internal block diagram (IBD); (d) measures of effectiveness (MoEs), which indicate the nonfunctional requirements, described in the SysML block definition diagram (BDD). The MoEs calculation procedures are specified with the SysML parametric diagrams.…”

MBSEsec: Model-Based Systems Engineering Method for Creating Secure Systems

“…The International Council on Systems Engineering (INCOSE) defines Model-Based System Engineering (MBSE) as the formalized application of modeling to support system requirements, design, analysis, verification, and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases [1]. Today, MBSE and the SysML language have become an indispensable part of designing complex cyber-physical systems [2][3][4]. The reasons for their popularity are [1-4]:…”
